It means exactly what it says; you have a world-writable directory, 
either / or /etc or /etc/mail.

What's the output of:
$ ls -ld / /etc /etc/mail

All should be 755:
$ ls -ld / /etc /etc/mail
drwxr-xr-x  38 root root 4096 Jan  4 10:27 /
drwxr-xr-x  87 root root 8192 Jan 11 05:34 /etc
drwxr-xr-x   3 root root 4096 Jan  7 09:55 /etc/mail

Less restrictive permissions than those represent a security issue.
